ROBERT GUNN, OF BUFFALO, NEW YORK.

DEVICE FOR OPERATING CAR-COUPLING PINS.

SPECIFICATION forming part of Letters Patent No. 407,070, dated July 16,1889.

Application filed May 1, 1889. Serial No. 309,170. (No model.)

T0 to whom it may concern:

Be it known that 1, ROBERT GUNN, a citizen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Devices for Operatingthe Locking-Pin of a Oar-Coupling, of which the following is aspecification.

The object of my invention is to provide a convenient and effectivemeans for raising, holding, and lowering thelocking-pin in that class ofcar-couplings known as the J anney coupling or other couplings thatrequire the pin to be raised and held in its elevated position until itbecomes necessary to drop it, all of which will be fully and clearlyhereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure 1 is a front elevationshowingaportion of the end of a car and my improved device connectedwith it. Fig. 2 is a side elevation of a portion of the front end of acar, showing the device in position for holding the pin up. Fig. 3represents a similar View showing the position of the several parts whenthe pin is down.

The coupling a 1d draw-head 1 is made in any well-known way and of theusual material; consequently a further description of this portion ofthe device is not required here. To the end of a car is mounted inbearings 3 an iron bar -l, adapted to turn easily in said bearings. Atone end of the bar l is secured in any well-known way, or formed in onepiece with it, as shown, a handle 5, located at or near the side of thecar, so as to avoid the necessity of going between the cars to operateit.

Projecting out from the bar 4 is an arm 6, connected with thelocking-pin 7 by means of a chain 8, and through the handle 5 is anopening through which is passed and pivoted by a pin 9 a curved bar 10,having a handle 11 at its forward end and a reduced portion ll, having ashoulder 12, at its opposite end. This curved bar 10 passes through asupporting guide-piece 13.

W'ith the class of car-couplings above mentioned during the operation ofuncoupling a car it is necessary that the locking-pin should be raisedup and held in its upward position until the uncoupling is'eifected. Theobject of my invention is to do this without the necessity of holding itup by hand, and the operation is as follows: \Vhile holding the pin '7up the handle 5 is drawn forward, as shown in Fig. 2, which operationallows the pivoted bar 10 to drop down until the reduced portion llrests on the bottom of the opening through the supporting guide-piece 13and the shoulder 12 rests against the lower side of the guidepiece 18.I11 this position the coupling or locking pin is kept securely in itsupward position until released by grasping the handles 5 and 11 by thehand and drawing them together, so as to raise the curved bar 10 andlift its shoulder 12 out of engagement. with the side of the guide-piece13. The handle 5 may now be pushed forward into the position shown inFig. 2, thereby dropping the locking-pin, as there shown.

I claim as my invention- A device for operating the locking-pin of acar-coupling, consisting of a bar 4, mounted in bearings at the end of acar and provided with a handle and an arm 6, in combination with acurved bar 10, pivoted to the handle 5, and provided with a handle 11 atits forward end and a shoulder at its opposite end, a guide'piece forthe curved bar to operate through, and a chain connecting with the arm 6and the locking-pin of a car-coupling, substantially described.

ROBERT GUNN.
